Implementation for QA/Testing for Tracking @a_akgun @mpeychet

• Learn & Plan about snowplow mini
• Get the access requests to setup a group project
• Setup GCP group project https://ops.gitlab.net/gitlab-com/group-projects/
• Setup Snowplow Mini with same Iglu config similar to production https://github.com/snowplow/snowplow-mini/wiki/Setup-guide
• Do we need Periscope testing possibility for PMs @mpeychet

Enabling other teams to use & conform to the process @sid_reddy @a_akgun @mpeychet @jeromezng

• Improve developer documentation https://docs.gitlab.com/ee/telemetry/#enabling-tracking
• Process from PM, to engineer to Telemetry to data should be documented
• Announce in backend, and growth other engineering teams
• Goal is to get product usage data from PM (question) to data [ insights ]
• In standard issue & MR templates let's have Data/Telemetry. We can also have pure data/telemetry issue and MR templates
